Don't believe us?? Well, the two were just spotted spending quality time in Monaco together after enjoying a holiday in Australia last month. Also, the Jason Bourne actor was ALL over the Thor hunk's Instagram this week.

Over the weekend, the Oscar winner hit the town with one lucky lady, and no, we're not talking about a date. Instead of cruising Tinseltown like the single man he is, Batman took his eight-year-old daughter Seraphina to a father-daughter dance. Cue all of the awwwwws!

And it appears as though the 44-year-old pulled out all of the stops for his kiddo as a source dished to E! News that Ben rented a limo to take them to the bash. Not to mention, the Live By Night director suited up for the dance and even gave little Seraphina a white corsage for her wrist. In an even cuter turn of events, the young Miz Affleck gave her poppa a boutonniere in return. It's like her first prom! How cute!

And it sounds like Ben and ex Jennifer Garner are still co-parenting away as she helped arrange the whole evening. In fact, the Alias alum helped Seraphina pick out a dress and get ready for the dance.

According to the insider, the evening was a hit for both father and daughter. The tipster dished:

"The two were walking around holding hands and he was very sweet with her. They both had a lot of fun dancing and hanging out with their friends."

Well, that's just adorable. We're glad this evening turned out so well for the father-daughter duo!
